Abstract
Device 7 for introducing air into a hydraulic system comprising a hydro-pneumatic reservoir 3 mounted on a pipe 1. The air introduction device 7 is mounted in such fashion as to introduce air into an area of the system containing water in which the pressure P.sub.s is either below or slightly above atmospheric pressure. The device is active when a lack of air is to be made good in the hydro-pneumatic reservoir 3.
Claims20
A device for introducing outer air into an hydraulic system in which a pipe is connected to a hydro-pneumatic reservoir is mounted on a pipe, said system having an area containing water in which the absolute pressure P.sub.s is below atmospheric pressure;
- said device comprising a means for introducing air into said area of the system containing water in which the absolute pressure P.sub.s is below atmospheric pressure, said means being active only when there is a lack of air to be made good in the hydro-pneumatic reservoir;
- said means for introducing air into said area of the system including:
- an air feed tube;
- an electric valve for allowing and closing off air flow through said air feed tube;
- and,
- an air introduction flowrate limiter for controlling air flow in the air feed tube.
